1. Patch your system by installing UltraUXThemePatcher
2. Copy contents from the Theme folder into C:\Windows\Resources\Themes
3. Apply theme in Settings > Personalization > Themes

Special thanks to niivu for guiding me through some stuff I was unsure about.

:heart: This theme does not cost any bells!
:heart: If you liked my work, feel free to purchase the paid version (no difference from free version)

I have a problem, I comply with all the steps to install the theme and it appears to me like this, is there anything I am recommended to do?

The patcher may not have worked, see first line of FAQ. You may need to take ownership of the 3 files yourself. Otherwise try using SecureUXTheme instead.

hello! this theme is so lovely, thank you so much for sharing it :D everything works perfectly besides winaero tweaker not allowing my taskbar font to stay as Nunito semibold. is there any way for it to consistently stay as nunito? also how do you get the start menu to look like the screenshot ;-;

undefinist's avatar

thank you! you need StartIsBack++ for the start menu, open the StartIsBack properties and apply the right taskbar / start menu.

I LOVE this, everything is perfect besides the top left button gets covered up in chrome. :c

undefinist's avatar

Try this:

  1. right-click chrome shortcut -> properties

  2. under Target, add --disable-windows10-custom-titlebar to the back (separated by space, so it should be something like "C:\Program Files (x86)\Google\Chrome\Application\chrome.exe" --disable-windows10-custom-titlebar

I followed what you said and it made no difference . even reset my pc u_u

undefinist's avatar

That's actually really weird. Are you opening through the shortcut?

Try running "C:\Program Files (x86)\Google\Chrome\Application\chrome.exe" --disable-windows10-custom-titlebar in the command prompt, just in case you're not. If it doesn't work anyways I'd suggest using NookX NC.

How to change my taskbar icons? They still white and not black :( When I use this theme, I can't see them

I'm using windows 10 1803

undefinist's avatar

They should be black if your system colors is in Light mode. Otherwise it'll be fixed by a new windows version, or you gotta modify the icons yourself.
